This article shows the steps to install NixOS in a node following the
configuration of the repo.
## Enable the serial console
By default, the nodes have the serial console disabled in the GRUB and also boot
without the serial enabled.
To enable the serial console in the GRUB, set in /etc/default/grub the following
lines:
```
GRUB_TERMINAL="console serial"
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"
```
To boot Linux with the serial enabled, so you can see the boot log and login via
serial set:
```
GRUB_CMDLINE_LINUX="console=ttyS0,115200n8 console=tty0"
```
Then update the grub config:
```
# grub2-mkconfig -o /boot/grub2/grub.cfg
```
And reboot.
## Prepare the disk
Create a main partition and label it `nixos` following [the manual][1].
